Phexological Observations, 1921 



The following report on the phenological observations of 1921 is 

 presented by Mr. F. F. Payne of the Central Ofifice of the Meteorologi- 

 cal Service. 



The number of phenological reports received from observers 

 other than those from Nova Scotia was 34, and although attempts 

 were made to enlist the services of others the increase over those of 

 1920 was only two. The work being purely voluntary and requiring 

 much attention only those deeply interested are inclined to take it up. 



The general summary for Nova Scotia kindly supplied by Dr. 

 A. H. MacKay, Superintendent of Education, Halifax, and prepared 

 by ten regional assistants is a model of the work which might be 

 undertaken by educational departments in other provinces and which 

 would be valuable for both educational and climatological purposes. 

 Credit is also due to Mr. W. H. Magee, Inspector of Schools, North 

 Battleford, for valuable assistance in procuring observers in Saskat- 

 chewan. 



In British Columbia vegetation during the Spring was somicwhat 

 backward but it improved late in May. In Alberta and Manitoba 

 early flowering plants were in bloom on dates in advance of the 

 normal but later growth was somewhat retarded. In Saskatchewan 

 vegetation generally made rapid progress in the Spring and the dates 

 of flowering were unusually early. In Ontario, Quebec and the Mari- 

 time Provinces the dates were considerably in advance of the normal. 



The Province of Nova Scotia is divided into its main climatic 

 slopes or regions which are not, in some cases, co-terminous with the 

 boundaries of the counties. Slopes, especially those to the coast, are 

 subdivided into (a) coast belts, (b) inland belts, and (c) high inland 

 belts. Where these letters appear in the tables they refer to these 

 slopes or regions. Dates for slopes IX and X were combined in 

 computing the average for the province. The following regions are 

 marked out, proceeding from south to north and from east to west as 

 orderly as it is possible.
